Platorm-specific fonts can be created by implementing a derived class with an override for the GetFont function. wxStockGDI operates as a singleton, accessed through the ms_instance pointer. By default this pointer is set to an instance of wxStockGDI. A derived class must arrange to set this pointer to an instance of itself. */ class WXDLLIMPEXP_CORE wxStockGDI { public: enum Item { BRUSH_BLACK, BRUSH_BLUE, BRUSH_CYAN, BRUSH_GREEN, BRUSH_YELLOW, BRUSH_GREY, BRUSH_LIGHTGREY, BRUSH_MEDIUMGREY, BRUSH_RED, BRUSH_TRANSPARENT, BRUSH_WHITE, COLOUR_BLACK, COLOUR_BLUE, COLOUR_CYAN, COLOUR_GREEN, COLOUR_YELLOW, COLOUR_LIGHTGREY, COLOUR_RED, COLOUR_WHITE, CURSOR_CROSS, CURSOR_HOURGLASS, CURSOR_STANDARD, FONT_ITALIC, FONT_NORMAL, FONT_SMALL, FONT_SWISS, PEN_BLACK, PEN_BLACKDASHED, PEN_BLUE, PEN_CYAN, PEN_GREEN, PEN_YELLOW, PEN_GREY, PEN_LIGHTGREY, PEN_MEDIUMGREY, PEN_RED, PEN_TRANSPARENT, PEN_WHITE, ITEMCOUNT }; wxStockGDI(); virtual ~wxStockGDI(); static void DeleteAll(); static wxStockGDI& instance() { return *ms_instance; } static const wxBrush* GetBrush(Item item); static const wxColour* GetColour(Item item); static const wxCursor* GetCursor(Item item); // Can be overridden by platform-specific derived classes virtual const wxFont* GetFont(Item item); static const wxPen* GetPen(Item item); protected: static wxStockGDI* ms_instance; static wxObject* ms_stockObject[ITEMCOUNT]; wxDECLARE_NO_COPY_CLASS(wxStockGDI); }; #define wxITALIC_FONT wxStockGDI::instance().GetFont(wxStockGDI::FONT_ITALIC) #define wxNORMAL_FONT wxStockGDI::instance().GetFont(wxStockGDI::FONT_NORMAL) #define wxSMALL_FONT wxStockGDI::instance().GetFont(wxStockGDI::FONT_SMALL) #define wxSWISS_FONT wxStockGDI::instance().GetFont(wxStockGDI::FONT_SWISS) #define wxBLACK_DASHED_PEN wxStockGDI::GetPen(wxStockGDI::PEN_BLACKDASHED) #define wxBLACK_PEN wxStockGDI::GetPen(wxStockGDI::PEN_BLACK) #define wxBLUE_PEN wxStockGDI::GetPen(wxStockGDI::PEN_BLUE) #define wxCYAN_PEN wxStockGDI::GetPen(wxStockGDI::PEN_CYAN) #define wxGREEN_PEN wxStockGDI::GetPen(wxStockGDI::PEN_GREEN) #define wxYELLOW_PEN wxStockGDI::GetPen(wxStockGDI::PEN_YELLOW) #define wxGREY_PEN wxStockGDI::GetPen(wxStockGDI::PEN_GREY) #define wxLIGHT_GREY_PEN wxStockGDI::GetPen(wxStockGDI::PEN_LIGHTGREY) #define wxMEDIUM_GREY_PEN wxStockGDI::GetPen(wxStockGDI::PEN_MEDIUMGREY) #define wxRED_PEN wxStockGDI::GetPen(wxStockGDI::PEN_RED) #define wxTRANSPARENT_PEN wxStockGDI::GetPen(wxStockGDI::PEN_TRANSPARENT) #define wxWHITE_PEN wxStockGDI::GetPen(wxStockGDI::PEN_WHITE) #define wxBLACK_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_BLACK) #define wxBLUE_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_BLUE) #define wxCYAN_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_CYAN) #define wxGREEN_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_GREEN) #define wxYELLOW_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_YELLOW) #define wxGREY_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_GREY) #define wxLIGHT_GREY_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_LIGHTGREY) #define wxMEDIUM_GREY_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_MEDIUMGREY) #define wxRED_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_RED) #define wxTRANSPARENT_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_TRANSPARENT) #define wxWHITE_BRUSH wxStockGDI::GetBrush(wxStockGDI::BRUSH_WHITE) #define wxBLACK wxStockGDI::GetColour(wxStockGDI::COLOUR_BLACK) #define wxBLUE wxStockGDI::GetColour(wxStockGDI::COLOUR_BLUE) #define wxCYAN wxStockGDI::GetColour(wxStockGDI::COLOUR_CYAN) #define wxGREEN wxStockGDI::GetColour(wxStockGDI::COLOUR_GREEN) #define wxYELLOW wxStockGDI::GetColour(wxStockGDI::COLOUR_YELLOW) #define wxLIGHT_GREY wxStockGDI::GetColour(wxStockGDI::COLOUR_LIGHTGREY) #define wxRED wxStockGDI::GetColour(wxStockGDI::COLOUR_RED) #define wxWHITE wxStockGDI::GetColour(wxStockGDI::COLOUR_WHITE) #define wxCROSS_CURSOR wxStockGDI::GetCursor(wxStockGDI::CURSOR_CROSS) #define wxHOURGLASS_CURSOR wxStockGDI::GetCursor(wxStockGDI::CURSOR_HOURGLASS) #define wxSTANDARD_CURSOR wxStockGDI::GetCursor(wxStockGDI::CURSOR_STANDARD) // 'Null' objects extern WXDLLIMPEXP_DATA_CORE(wxBitmap) wxNullBitmap; extern WXDLLIMPEXP_DATA_CORE(wxIcon) wxNullIcon; extern WXDLLIMPEXP_DATA_CORE(wxCursor) wxNullCursor; extern WXDLLIMPEXP_DATA_CORE(wxPen) wxNullPen; extern WXDLLIMPEXP_DATA_CORE(wxBrush) wxNullBrush; extern WXDLLIMPEXP_DATA_CORE(wxPalette) wxNullPalette; extern WXDLLIMPEXP_DATA_CORE(wxFont) wxNullFont; extern WXDLLIMPEXP_DATA_CORE(wxColour) wxNullColour; extern WXDLLIMPEXP_DATA_CORE(wxIconBundle) wxNullIconBundle; extern WXDLLIMPEXP_DATA_CORE(wxColourDatabase*) wxTheColourDatabase; extern WXDLLIMPEXP_DATA_CORE(const char) wxPanelNameStr[]; extern WXDLLIMPEXP_DATA_CORE(const wxSize) wxDefaultSize; extern WXDLLIMPEXP_DATA_CORE(const wxPoint) wxDefaultPosition; // --------------------------------------------------------------------------- // global functions // --------------------------------------------------------------------------- // resource management extern void WXDLLIMPEXP_CORE wxInitializeStockLists(); extern void WXDLLIMPEXP_CORE wxDeleteStockLists(); // is the display colour (or monochrome)?
